WASH-TUB.

SPECIFICATION forming part of Letters Patent No. 416,452, dated December 3, 1889.

Application filed May 4, 1889- $erial No. 309,643. (No model.)

To all whom it may concern.-

Be it known that I, FREDERICK F. FIELD, of the city and county of Providence and State of Rhode Island, have invented a new and useful Improvement in VVash-Tubs, of which the following is a full, clear. and exact description, reference being had to the accompanying drawings, forming part of this specification.

This invention has reference to an improved construction of wash-tubs; and it consists in the novel and peculiar construction of a tub formed of a single sheet of material, as will be more fully set forth hereinafter.

The object of my invention is to form a wash-tub of one sheet of material, without either joint or seam, which shall have suiticient rigidity to withstand the necessary wear, and to this purpose I form a sheet of metal or other suitable material into the shape of a tub, having flaring funnel-shaped sides, by crimping or corrugating the surplus material of the sheet, and thus form corrugated sides to the tub, the corrugations diminishing downward until they end near the bottom, and strengthen the upper edge by a rigid rim formed to'fit the corrugation of the sides, as will be more fully set forth hereinafter.

Figure 1 is a top View of my improved wash-tub. Fig. 2 is a vertical sectional view of the same, showing the original sheet in broken lines.

In the drawings, similar numbers of reference designate corresponding parts throughout.

The bottom 3 and horizontally-extending broken lines 4 represent a circular sheet of metal, straw-board, leather-board, wood pulp, or other material suitable for the purpose.

5 5 are the corrugated sides, formed by bending the portion ,4 of the sheet upward and inward, utilizing the surplus material of the circular sheet by corrugating the same, as is shown in the drawings, and thus forming the bottom and sides of a tub out of one piece, without joint or seam.

6 indicates a rim, which maybe made of wood or any other suitable material. The rim may be placed on top of the corrugated sides by providing the rim with a groove into which the corrugated sheet enters; or it may be placed against the corrugated sheet on the outside by forming the same to fit into the corrugations, so as to stiifen the same. In practice I prefer to place the rim on the outside, as is shown at 7 in section.

\Vash-tubs made of staves must be made round; but soapstone and other wash-tubs are usually made square. I find that a flattened portion 8, as is shown in Fig. 1, makes the use of the wash-tub more convenient to the washer. I also find that the corrugated sides soon become of considerable value in washing, particularly on the flattened side 8, for cloth forced down on the gradually-diminishing corrugations, or laterally over the same, is rubbed sheet against sheet in a manner that facilitates washing.

It is obvious that, if desired, handles may be secured to the wash-tub.

Having thus described my invention, I claim as new and desire to secure byLetters Patent A wash-tub formed from a single sheet by corrugations made in the sheet around the bottom to form the sides, stiifened by a rim formed to receive the upper edge of the sides and secured thereto, having the flattened side 8, forming a secant of the circular-plan form, as described.
